"Air", Part 1
This unnamed galaxy was the first one unwittingly visited by the Destiny crew members in 2009. They eventually left this galaxy to another one.
According to Dr. Nicholas Rush, the galaxy is located several billions lightyears away from Earth (SGU: "Air", Part 1).
An Ancient seed ship passed through the galaxy and seeded many Stargates on planets and gathered informations for Destiny for the moment she'll pass as well.
